Homini -CY IND R Ion To all whom it may concern:

Be it known that LFnnnnnrc-n-E-Sfihrnn,

a citizen of the United States, residing. at Idaville', in the county of White and State of Indiana, have invented a new and useful Hulling- Cylinder for Glover and Alfalfa Hullers; and I'do hereby declare the following' to be a full, clear, and exact description of the invention, such as will enable others skilled inthe art to which it makeand use the same."

This invention relates to, an metal hulling cylinder designed'for use-in connection with clover and alfalfa hullers andthe like. 1

One of-the objects of the invention iis the provision of a cylinder preferably constructappertains to ed of sheared rolled steeLand where the adjacent edges of the steel plate are located an angular strap is bolted to the adjacent portion of said plate, thereby holding said adjacent edges separated, forming an opening or slot, in which the hulling rasp bands are arranged, to hold the bands in position. Another feature of the invention is the provision of end cylinder rings to prevent endwise movement of the rasp band.

Another object of the invention is to con- 'struct the cylinder entirely from suitable metal, thereby dispensing wi h the employment of wood, screws and nails.

Another object of the invention is to provide a simple, efficient, practical, inexpensive and substantially indestructible hulling cylinder, which will only necessitate but a few moments to remove the old rasp bands, for the arrangement of new ones, and in no way requiring the use of nailsand the like, whereas as in the old form or construction a multiplicity of nails must be driven, :in order to renew the rasp bands. v Another object of the invention is to provide an improved cylinder havingmeans to prevent the rasp bands from becoming loose, while the cylinder is in operation.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

In the drawings: Figure 1 is a view'in perspective of the improved cylinder constructed in accordance with the invention. Fig. 2 is a longitudinal sectional view on line 2-2 of Fig. 1. Fig. 3.is a perspective view of the cylinder showing the rasp bands removed. Fig. 4 is a longitudinal sectional view, which view extends longitudinally 1 improved oLovnnnnD atmn jn mms. 2'

2 Referring more especiallytothei'idraw ings, .1 Zdesignates a shaft, Ion which the cylinder heads2 and-3- are keyed. orofeathered,

as shown at 4:; Also arranged on the shaft is a central spiderimembery 5, comprising 'a hub "6 and radial arms 7 and'the'ring 8, which are securedtozthei casing 9 of the cylinder. The'casing-9 of'thecyli-nder is co nportions of; which are bolted or rivetedias "shown" at 10=to theilateral fianges 11 oflthe so as to hold the. adjacent edges spaced apart as shown. Moreover, the angular por-- tions 16. are spaced or offset from the adja-fj cent edge portions 17, to form the recesses 18. Where the plate or strap 15 is arranged the end cylinder heads and the ring 8 of the centralspider are'recessed, to receive the plate or strap 15. The rasping bands 19 which are constructed of singlelengths of sheared rolled steel having outer .rasping the slot or opening 14. The parts 22 of the angular ends 21 of each band are received in the recesses 18, said recesses being of sizes corresponding to the size of said parts 22, so as to closely receive said parts. The adjacent end portions 17 are separated only sufficient to form the slot or opening 14 of a size just sufficient to receive the thicknesses of the'two angular ends 21 of said band, so as to hold theband securely thereon. It is to be noted that the bandsare inserted or arranged on the cylinder endwise thereof, the angular ends 21 and the parts-22 entering the slot-or opening 14: and the recesses 18. To prevent endwise movement. of the bands, after they are arranged on thecylinder end structedof sheared. rolled steel, the .endedge edge portions 16 bolted to the cylinder plate,

surfaces, are fitted snugly upon the cylinder, one closely adjacentthe other, and are pro- 'vided with angular ends 21 to be received in r cylinder rings are provided, and these rings 24 are bolted to the end flanges ll of the cylinder head, by means of tapered bolts 25.

These rings 24 are of suflicient diameter that is, from opposite peripheral portions, in order to project beyond the cylinder wall proper, in order to form flanges as shown, to hold the rasping bands in place.

A cylinder constructed in accordance with the inventionand provided with a rasping band is designed to cooperate with a suitable concave 26, which may be constructed of sheared rolled steel and shapedto form a siderably less time than heretofore, especially in renewing the rasping bands.

v The invention having been set forth, what is claimed as new and useful is LA. hulling cylinder comprising cylinder heads having laterally extending annular flanges, said flanges being constructed to form transverse channels being alined, said channels having adjoining recesses, an elongated strip being bent to form a longitudinally extending channel and having longitudinally extending flanges to seat in said recesses, said channeled strip engaging the channels of the flanges and connecting said heads, a sheet metal cylinder wall having its adjacent longitudinal edges spaced apart and partially overlying the channel in the strip, a plurality of rasping bands fitting the exterior of the cylinder wall and having angular adjacent ends extending between the longitudinal adjacent edges ofthe wall and engaging under the portions of the wall which overlie the channel of the strip, and means bolted to the cylinder heads to prevent endwise movement of the rasping band.

In testimony whereof I have signed my .name to this specification in the presence of two subscr bing WltIlGSSBS.
